The main object of this invention is to provide an attachment for gasvalves having a handle which moves the valve shank,I and the purpose ofthe device is to enable 3 the user to automatically latch the valvehandle in the closed, completely open, or

intermediate positions so that any amount characters of reference referto like-named y parts in the drawings.

Referring briefly to the drawings, Figure 20 1 is a perspective View ofthe valve attachment, showing it as applied to a valve.

Figure 2 is a top plan vien7 of the valve attachment per se. Y

Figure 3 is an end elevational view of the device.

Fi ure 4 is a longitudinal, partly sectioned, front elevational View ofthe device, showing the means of depressing the latching valve.

Referring in detail to the drawings, the numeral indicatesthe fuelsupply pipe which is connected to the main atV one end. These fuelsupply pipes are applied, and form a unit with, gas ranges and similarother gas burning devices. To the fuel supply pipe a series of valves,such as those indicated by the numeral 11, are tapped. These valves arearranged in series and are spaced-apart from each other. These valvebodies are commonly provided with a ltapering shank in which a port islocated, said port, when in open position, permitting communication withthe gas fuel Asupply pipe and the burner sleeve 12,- vThe one nipple ofthe valve body is, as previously mentioned, tapped to the gas supplypipe 10, while the other nipple 13, diametrically opposite, is insertedinto the capped end 14 of the burner supply sleeve 12. The shank of thevalve, whose upper end 15 is exposed, is rotatably mounted fin thevalve.V This upper end of the shankisy surmounted spherical member 16from which a p handle bar 17 extends at right-angles vto the y, shankand is adapted to be rotated in a 55 horizontal plane.

Attached to the nipple which taps into the v fuel supply pipe 10 is asplit clamp consisting of a semi-circular strap 18 and anindependentsemi-circular strap 19, which lat- 60 ter is secured to the former byscrews or sim- `ilar. other devices, and' is complemental to member. 18.lThe clamp member V 18 is' secured to a segmentalflat plate 2O positionzfed above the gas fuel supply pipe 10. Said S plate isl provided with aAcurved slot 21, concentric about the axis vof the shank 15. and isoverninetyA degrees of, arc in length so thatthemember traveling in theslotis capable of following the handle'bar 17 from I7o the closed to theopen position. Adjacent Vthe slot 21 a lplurality of equallyV spaced-Aapart openings 22 are provided and are also generated about the axis ofthe shank' 15. Thei'slot 21, formed in the plate, has Inovr'1li abletherein the lower lend of a stud 23. This lower endof said member isflanged with members 24 and 25 on both sides of the plate 20 so thatsaid stud 23 cannot be displacedV from the device. KYNear the.` upper`80 end of the stud 23 a collar 26 is'located and, surmounting thiscollar, is Va fork 27, which latter is adapted to receive they handle,bar y 17'of the valve.

' A hollowv barrel envelopesfthe major portion of the shank and, when inloweredpor'Vsitiom the upper closed end of the shank is ,adapted to come@to yrestrupon the collar 26.

The lower end ofthe barrel is provided with ihn va closed face, and,when the barrel is in lowered position, lseats upon the Hange25. Thebore 29 of. saidbarrel has a coil spring 30 therein. This coil spring iswound about 'the stud y23,v seats upon` the lower face 31 of g5 thebarrel, and, at its upper end, contacts with the',colla1"26.` "A vpairof L-shaped v'latch' prongs *project* fromv the sideV of the Vbarrel-,28and are ad'apte'dotov be urgedV into 'fflly 'Pal 0f openings 22'by thetension ofthe 100 Y the device is ready for use. By pulling the barrelupwardly the latching prongs 32 and spring 30 as these prongs pass anypair of openings in the plate 20. Y

rllhe device is adapted to serve as a safety latching unit forpositively securing thel valve shank in either the open, the closed orany of a number of intermediate positions. The plate is secured'in itsdesired location by removing the-independent clamp member 19 and seatingmember 18 rigid with the plate 20 over one of the nipples of theyalvebody 11. vThe strap`19 is then agaiiisecured in place on theopposite side of the nipple, but, before this is done, the plate is sopo-A sitioned beneath the valve handle 17 that it may accommodate thereception of the valve handle 177 within the fork V27. The bore 29 of.the barrel, and the collar 26 mounted therein, are square 'in outline sothat the barrel may ynotbe rotated uponV the stiidv23. y After theplatefhas been secured in place 33 arefretracted'out of any vpair ofopenings 22 lafter which 'the handle bai' 1,7 of the valve is free to berotated. By releasingithe barrel the latch pegs are'perinitted to slideupon the surface of the plat-e and these latch pegs, when arriving atthe next opening, will immediately plunge into these openings and Vagainlatch the handle bar in a new posito said handle bar, a barrel slidableon said stud, latch pegs depending from said barrel c tures.
